As for \hcenter and \column, should I leave these as duplicates of
\center-align and \left-column (which would help minimize user
complaints), or remove them?
I just realized that \column and \left-column isn't the same thing
(or at least that it shouldn't be the same thing). If you compare the
implementation of the current \column and \center-align commands,
you will notice that \column just stacks the markups using their
already existing horizontal alignment points, whereas \center-align
also sets the horizontal alignment point of each markup in the column.
In other words, \center-align is equivalent to \column \hcenter, as
the following example illustrates:
\version "2.11.50"
\markup{\column{ \left-align { AAAAA BBB C }}}
\markup{\column { AAAAA BBB C }}
\markup{\column{ \hcenter { \right-align AAAAA BBB C }}}
\markup{\center-align { \right-align AAAAA BBB C }}
Similarly, a \left-column that does what the name says, should
explicitly set the horizontal alignment point of all the markups
to be left aligned, i.e. be equivalent to \column \left-align.
The following example illustrates the difference:
\version "2.11.50"
\markup{\column { \right-align AAAAA BBB C }}
% What a proper implementation of \left-column should do:
\markup{\column{ \left-align { \right-align AAAAA BBB C }}}
